[ofw] Opensm & WinMad: a race, causing BSOD722

[Smith, Stan]

Data point: the head of SVN builds and installs correctly and validates correctly for Connect-X2 and Infinihost on the 6 systems (2 CX + 4 InfiniHost) I tested.

I swapped the HCA with one from another system, but still see the error. The
OFED 3.0 release works fine. I will try backing out my changes and testing
with the head of the svn tree tomorrow or early next week, though I don't see
why the changes would affect loading the driver.

Ok, my build went faster than I expected. I was able to apply this patch to the 3.0 code release and verify that it at least doesn't crash the
system.

The HCA information from my system is below. Stan, if you can send me a pointer offline, I'll try installing using your build to verify that I wasn't picking up some old installation.

I updated to FW 2.9.1 and the tip of svn worked again. IMO, the latest drivers should not automatically break a working HCA just because the firmware is older (was 2.7).
